much more running concurrently, is something I can't really speak to, but I
would guess there's a point where increasing it could cause issues
depending on total memory available and how many processes are getting
memory reservations from the kernel.
For what it's worth, our friends over at SUSE have a kbase article on the
possible side-effects of increasing this setting. Find it at
https://www.suse.com/support/kb/doc/?id=000016692. (In short, the
consequences are that processes which map more memory can do so, which is
bad for memory usage overall and can hurt performance.)
